It seems no one knows this game has command line flags. I figured these out while making my file extracting tool and thought I should document them somewhere. Enabling the log was very helpful in working through the game's archive file format. The most useful flag for most users will probably be that for windowed mode.

If anyone wants to mod this game (such as making a translation) let me know as I have a way to do it. If anyone has any corrections to this document please comment.
